No, but is that so important? If we can fix cell and tissue degeneration we're likely to prolong life span and improve quality of life dramatically. We can do the rest when we get there.

It's certainly a necessary condition to prolong life but I would hold the "dramatic" epithet until we get there.

Once down the rabbit hole, we might well encounter an endless barrage of other genomic self destruct clocks.
